Vegetarian Diets Vegetarianism includes a wide variety of eating patterns buy generic doxazosin 4 mg on line, and today there is widespread dissemination of information demonstrating that appropriately planned plant-rich omnivorous diets and plant-based lactovegetarian and semi-vegetarian diets are equally successful in promoting health generic 2mg doxazosin free shipping. The health-promoting effects of plant foods are thought to be to the result of various compounds found in them 2mg doxazosin overnight delivery, only some of which are nutrients in the classic sense order 4mg doxazosin amex. Consumption of a vegetarian diet is a typical alternative therapy among patients with rheumatoid diseases, including patients with fibromyalgia. Fasting has also been used because it may decrease inflammation owing to energy deprivation. In all of these studies, there have been patients who have both subjectively and objectively benefited from a vegetarian regimen. Some supplements have been shown to nonspecifically inhibit inflammation (29), so benefits are not limited to patients with fibromyalgia. The research interest has varied from the nutrient content to the possible therapeutic effects of the diet. Food items such as berries and wheat grass juice are rich in antioxidants including carotenoids and flavonoids (38). The first intervention conducted on patients with rheumatoid diseases (7,21) as well as the other one on patients with fibromyalgia (22) revealed that Finnish rheumatoid patients energy and some nutrient intakes were below the recommended levels of intake. Dietary modification among patients with fibromyalgia led to an increased intake of vegetables, fruits, and berries such that twice the amount consumed on a mixed diet was achieved (40). There was no change in the total intake of energy, but the proportion of energy from carbohydrates was higher and that from protein lower during the intervention. In both studies, subjects in the intervention groups ate living food for 3 months, wheras the control patients continued on their omnivorous diet. The fibromyalgia intervention was an open, nonrandomized controlled study that presumably helped patients to follow the diet more strictly and longer compared with the rheumatoid study where patients were randomized. The fibromyalgia impact questionnaire score was reduced by 46%, from 51 to 28 (n = 20). Significant improvements were seen in shoulder pain at rest and after motion, abduction range of motion of shoulder, flexibility, and in the 6- minute walk. Of the whole group, 19 subjects were responders who showed significant improvement on all measured outcomes, whereas rest did not benefit from the diet. The authors concluded that many patients with fibromyalgia can be helped by a mostly raw vegetarian diet. If these two studies are compared, one probably significant difference has been the content of lactobacilli in the intervention diet. The results of a small pilot study in 18 patients with fibromyalgia (29) suggested that the addition of Chlorella pyrenoidosa to their diet produced a significant reduction in pain after only 2 months. Almost 50% of the patients expressed that some of their other symptoms had improved. Presumably, the healing takes place because of its capacity to nonspecifically enhance immunological reactions (29). However, identification of similar patients and much more research must be performed before definitive conclusions concerning causation can be made. They are also released by neutrophils and macrophages when they fight against bacteria and other agents causing inflammation. They receive high amounts of exposure to ultraviolet light that generates radicals in tissues. Furthermore, during photosynthesis, oxygen in statu nascendi is generated in their chloroplasts. When the plants are oxidizing nutrients, their mitochondria are releasing oxygen-derived radicals, as do animal cells. This means that the plants must be very well prepared to meet the challenges of the radical-induced stress. The plants contain, therefore, a broad variety of antioxidant chemicals in addition to the enzymes catalysing their interaction. Oxygen-derived radicals are part of life in all aerobic organisms, humans included. Measurements of antioxidant levels in vegetarians show that a vegetarian diet maintains higher antioxidant vitamin status (vitamins C and E and -carotene) but variable antioxidant trace element status as compared with an omnivorous diet (43). Consequently, compared with the matched omnivores, the living-food eaters had significantly higher blood concentrations of -carotene and vitamins C and E, as well as higher erythrocyte superoxide dismutase activity (38). A good individual source is also a wheatgrass juice, which contains a lot of lycopene and -carotene. In our study (38) we found that some long-term vegans had serum -carotene concentrations exceeding those achieved by supplementation with 20 to 30 mg pure -carotene. Additionally, it houses a rich microflora environment that carries out valuable tasks (e.

Esas difcultades deben pillarnos unidos y con una estructura fuerte, capaz de aguantar crticas, eventuales desnimos e incluso abandonos. Otro poeta, ngel Gonzlez, ha escrito: The llaman porvenir/ porque no vienes nunca, y enseguida: Maana! Efectivamente, nos cansaremos de esperar ese futuro feliz que anhelamos, el maana de una Pennsula Ibrica poblada por linces en gran parte de su extensin, sin mayores problemas. Pero hemos de hacerlo porque, aunque el hoy no sea tan malo como hace diez aos, el incierto maana sigue siendo nuestro. We became aware of the disastrous situation of the Iberian lynx only a decade ago. Paradoxically, A as it sometimes happens in politics, only after hitting rock bottom did we start to go up again, but we decided to do it together and we are rising. Therefore, our today is not worse than yesterdays dream of tomorrow, and the ex situ conservation programme has a lot to do with this. Quite a few years ago, the Spanish Ministry of the Environment organised and chaired a meeting of the Working Group on the Iberian lynx, which has been unjustly forgotten and was unfortunately terminated. To achieve this, we had to come out of the darkness and shed some 519 light on these issues, in spite of the obvious risks involved. First, we needed to know and say where the lynx was present to optimise efforts and resources. Back then, I remember saying that we needed urgent measures with the structure of a stool. I mentioned three legs and a seat, a horizontal surface bringing the legs together. The frst and most urgent of the legs was to try to stop the haemorrhage, to slow down the population decline; it seemed useless to design the future of the lynx if we did not guarantee its presence in areas where it still occurred. The second leg involved confrming the presence of the species in favourable areas where little sampling had been done, or where very few individuals might still be left; we should also guarantee the conservation of enough habitat in those areas and others for other lynx populations apart from the known ones to be able to exist in the near future. The third leg referred to artifcial measures to create or consolidate new populations; such measures ranged from the translocation of wild individuals to other areas to captive breeding of animals for later release. I wrote about this at the time, saying We must learn to breed lynx in captivity as a last resort, and there is already a good plan on how to do it. Most of these proposals have been included in the recently adopted Spanish National Strategy for the Recovery of the Iberian Lynx, which Portugal seems to willingly adhere to (it would be good to set up an offcial Iberian Strategy, by the way). Indeed, the Regional Government of Andaluca and the Spanish Ministry of the Environment grabbed the bull by the horns at that point and the ex situ conservation programme that this book is about is now a brilliant reality. The captive breeding programme has done much more than just provide the specimens needed to try to recolonise lost areas and be a safety net to allow us to work with greater confdence on the edge of the abyss. Beyond all this, the captive breeding program, headed by its director, has proven to be the most energetic and transparent driving force of lynx conservation in situ as well. This is worthy of praise (and unanimously praised), but I honestly consider that it is an excessive burden for the ex situ conservation team and the people who head it. They did it because it was necessary and nobody was doing it, because we did not know how to or we simply were not able to. Until very recently, our meetings were held in a desperate mood, with the only objective of preventing the extinction of the species, which was seen as almost inevitable. Almost without noticing, we have recently started to discuss how to ensure that the lynx returns to Portugal and the Spanish regions where the species recently disappeared. The expression Yes we can has become popular after Obama used it and won by a landslide. With the inevitable ups and downs in a world and an economic system that do not inspire optimism, at least for nature conservation, in the case of the lynx we now believe in our own work. Yet, I was saying that the people in charge of the ex situ conservation programme cannot continue to do everything. My feeling today is that the structure upholding the recovery of the Iberian lynx is basically composed of just a few people. They are strong poles, but might break and will eventually break if work is not shared by others. Inevitably, we will sometimes fail; even when good results are obtained, people will sometimes see them as being negative (e. When these diffculties happen, we must be united and have a strong structure that can withstand criticism, possible discouragement and even resignations.

In an attempt to establish criteria for diagnosis that also serve as a common basis for research homogeneity and comparison of the results, after several revisions worlds authorities have reached a consensus (11) (Table 7. The other four criteria identify objective signs and need a more detailed discussion. The wetting of the paper is measured after 5 min and if found less than 5 mm, the test is considered positive.

The criteria, the authors follow a classification tree that reveals Ro/La antigenic system consists of three different proteins, with great sensitivity (96. In addition, the multiplicity of these antigens accounts in part for differences in laboratory methods of their measurement. What should also be kept in mind is that the criterion should lie not only to one diagnostic procedure antibody levels do not correlate with disease activity but two so that specificity is maintained (15). Finally, emphasis is given to the fact expected, subjective symptoms and objective findings do that these criteria are classification criteria and their not always correlate; in fact there is a wide dichotomy of purpose is to aid research and communication among subjective to objective manifestations especially in patients scientists and not serve as a diagnostic tool.

Beyond this discount doxazosin 2 mg on line, the conservation breeding programme provides insight into particular questions such as reproductive biology or health problems and diseases that could affect the species generic 1 mg doxazosin overnight delivery. Findings as a result of captive breeding quality doxazosin 1mg, such as the study of pathogens and the observation of sibling aggression among lynx cubs have immediate consequences for the management of both the captive- and the free- ranging populations order doxazosin 1 mg line, and last but not least, the captive breeding programme helps to raise worldwide awareness for the fate of the Iberian lynx and its conservation needs. The Iberian lynx conservation process and its captive breeding programme follow an interdisciplinary approach, emphasised by the wide range of topics covered in this book. The present book summarises the experiences presented in the talks, all of which have been updated to cover the work that has taken place in the conservation breeding programme between 2004 and 2008. The frst section presents a review of the in situ situation and feld conservation activities. The second section deals with genetic aspects and the behaviour and husbandry of Iberian lynx in captivity. The third section compiles papers on veterinary aspects and health issues, which became increasingly important in recent years. The fourth section looks at reproductive physiology of a variety of felid species, placing special emphasis on the latest fndings on lynx reproduction. Lastly, the ffth section provides an overview of reintroduction techniques and case studies of felid reintroduction projects. The chapters compiled in this publication represent the collaborative international work carried out towards the conservation of the Iberian lynx during the past five years, but also portrays similar studies and approaches from other felid species from various areas of the world. Each chapter has been treated as a peer-reviewed paper for a scientific journal, and has been revised by three different experts in the specific subject. Although the books main language is English, abstracts and illustration captions from each chapter are presented in both English and Spanish; the prologue, preface and epilogue are also offered in both languages. While presenting scientific research in a wide variety of disciplines, the book also hopes to appeal to the eye of the viewer by including more than 200 photographs contributed by national and international photographers. World renowned photographic artist Joe Zammit-Lucia, has specifically designed the photographs that appear in the front and back covers, as well as the artwork in the opening page of each of the sections. The verses and quotes that appear throughout the book have been largely selected by the authors. The variety of themes together with the selection of experts and authors from across the world demonstrates that the Iberian lynx needs international support for its survival, and also reveals how the global conservation society is interested and involved in the recovery of this species, emphasizing how much we all need to work together to prevent the extinction of this magnificent cat. But if he spends his days as a speculator, shearing off those woods and making the earth bald before her time, he is deemed an industrious and enterprising citizen. Esta especie de lince presenta una alta especializacin en cuanto a sus necesidades alimenticias y de hbitat: consume casi exclusivamente conejos europeos y habita en zonas mediterrneas de monte bajo. Las hembras normalmente se reproducen una vez al ao entre los 3 y 9 aos de edad, y suelen sobrevivir slo 2 de las 3-4 cras que nacen en cada camada. Los linces jvenes abandonan el territorio materno cuando tienen entre 1 y 2 aos de edad, momento en el que se dis- persan en bsqueda de nuevos territorios donde asentarse como residentes. El rea de campeo de los linces adultos ocupa entre 4 y 30 km, dependiendo 2 de factores como el sexo y la densidad de conejos. Los territorios de los machos y hembras adultos pueden coincidir en gran parte, pero esto no suele ocurrir en- tre ejemplares adultos del mismo sexo. En la naturaleza, el lince ibrico tiene una mortalidad elevada por causas no naturales, especialmente fuera de las reas protegidas. This lynx species is highly specialized in its diet and habitat requirements, consuming almost exclusively European rabbits and inhabiting Medite- rranean scrubland. Females normally breed once a year between 3 and 9 years of age, and only 2 of the 3 kittens of the litter usually survive. Between 1 and 2 years of age juvenile lynx abandon their mothers territory and disperse in search of new territories to settle as residents. The home ranges of adult lynx measure between 4 and 30 km,2 depending on factors such as sex and rabbit density. Core areas greatly overlap between adult males and females, but there is no overlap between adult individuals of the same sex. In the wild, the Iberian lynx experiences a high mortality from non-natural causes, particularly outside protec- ted areas. Two lynx species the Iberian lynx and the Eurasian lynx (Lynx lynx) occur in Europe and Asia, and two other species the bobcat (Lynx rufus) and the Canada lynx (Lynx canadensis) occur in North America. About one million years ago, a population of Cave lynx became isolated in south-west Europe and gave rise to the Iberian lynx as we know it today. Whereas individuals in the Doana area have a pattern of large dark spots and stripes on a tawny background, those in Sierra Morena have small, less distinct spots on a more or less grayish background. The Iberian lynx is currently the worlds most endangered felid species (Novell and Jackson, 1996). Unlike the other lynx species, the Iberian lynx already had a small natural range which was limited to the Iberian Peninsula. After a very dramatic decrease in the size of its range in recent decades, only two populations remain in southern Spain Doana and Eastern Sierra Morena. Fe e d I n g e c o l o g y The Iberian lynx feeds almost exclusively on rabbits (Delibes, 1980).
